Patent CA-3019968-A1 (CA)
Inventor: KOWALCHUK TREVOR
IPC: A01B71/00
Filed: 2013-09-20
Abstract: A method and system for controlling operation of a tractor and/or agricultural implement towed by the tractor is disclosed. A vibration sensor is mounted to the agricultural implement to detect the magnitude of vibration, or bounce, on the agricultural implement. Because the magnitude of the vibration is a function of several operating parameters including, but not limited to, the speed at which the tractor is travelling and the downward pressure applied to the agricultural implement, one or more additional sensors are provided to monitor these operating parameters. Each of the sensors generates a feedback signal and transmits it to the controller. The controller is configured to generate an reference signal to control an actuator as a function of the magnitude of vibration and the measured operating parameter. The actuator receiving the reference signal is configured to control operation of the tractor or agricultural implement to reduce the magnitude of vibration.

Title: A method for preparing high-purity chlorine dioxide by using methanol and hydrogen peroxide as reducing agent
Inventor: WANG SHUANGFEI
IPC: C01B11/02
Filed: 2018-08-30
Abstract: The invention discloses a method for preparing high-purity chlorine dioxide by using methanol and hydrogen peroxide as reducing agent. The method comprises:  concentrated sulfuric acid and sodium chlorate solution are injected into the generator to form the reaction mother liquid. The reaction mother liquid shall be maintained a certain acidity, temperature and sodium chlorate content, and then it is reacted with the reducing agent (methanol and hydrogen peroxide) to produce chlorine dioxide gas and by-product sodium sulfate. The chlorine dioxide gas is cooled and absorbed by low temperature chilled water to obtain an aqueous solution of chlorine dioxide, and by-products are recycled. The chlorine dioxide solution produced by the aforementioned method has a 60-70% reduction in the Cl2 content and 14-20% reduction in sulfuric acid consumption than that of the chlorine dioxide produced by using a single methanol reducing agent, and the by-product produced is sodium sulfate, not sodium hydrogen sulfate, so neutralization reaction treatment is not required.

Title: Method of selection of asphaltene precipitant additives and process for subsurface upgrading therewith
Inventor: OVALLES CESAR
IPC: E21B43/34
Filed: 2019-02-01
Abstract: In-situ upgrading of heavy hydrocarbons includes injecting into a reservoir solvent, an asphaltene precipitant additive and optionally steam, at a ratio of solvent to heavy hydrocarbon between 0.1:1 and 20:1 under reservoir conditions. The additive has C-H, C-C  and/or C-O bonds that thermally crack to generate free radicals in the vapor phase after injection. Formed downhole are a blend containing an upgraded hydrocarbon, and precipitated asphaltenes. The upgraded hydrocarbon is produced such that the precipitated asphaltenes remain in the reservoir.  The upgraded hydrocarbon has a greater API gravity, lower asphaltene content, and lower viscosity than the heavy hydrocarbon. The precipitated asphaltenes are present in a higher amount than a similar blend not containing the additive. A method for selecting the additive includes identifying candidate additives having bonds that crack to generate free radicals in the vapor phase at the operating temperature, and calculating percent increase of asphaltenes precipitated for each.

Patent CA-3034826-A1 (CA)
Inventor: DAVIS JOSEPH MICHAEL
IPC: G06F16/24
Filed: 2017-09-29
Abstract: The present approach improves the query performance of a database in a manner that is transparent to a user. In one aspect, this approach creates separate partition tables that are not directly accessible to a user of the database. A client-facing aspect of the database is a logical model which may correspond to a single, main table with which the user interacts. Thus, queries or operations may be generated on the client side in the context of the logical model. A database or query layer can then, transparent to the user, translate the user generated requests into query language that addresses the proper partitions to generate a result set or otherwise perform a database operation.
